Definitions

  • the invention relates to a damping device for interference currents which are superimposed on an operating current and have a higher frequency than the operating current, at least consisting of an inductance through which the operating current flows.
  • the object of the present invention is now a damping device for electronic consumers using the special properties of the nanocrystalline and / or amorphous materials with a relative permeability of over 20,000 in order to produce a damping of interference currents of electronic components in a wide frequency range, without the need for special components.
  • This object is achieved in that an inductor made of amorphous or nanocrystalline material with a relative permeability of more than 20,000 existing toroid is applied to a pin inside the housing of a plug connection.
  • the housing 1 is shown consisting of two joined parts 2 and 3.
  • the pins 4 are fastened in a holding body 6 via insulation material 5 and are, for example, at a distance of 3 mm from one another.
  • the part 3 is at a distance from the holding body 6.
  • the intermediate space thus formed is used according to the invention to accommodate cores 7, which consist of amorphous or nanocrystalline tape.
  • the material of these cores has a relative permeability of over 20,000 and thus gives the pin 4, which surround them, an inductive resistance that prevents high-frequency interference currents and thus significantly improves the electromagnetic compatibility of the device connected to the plug, without additional space for damping devices is available.
  • a further improvement can be achieved if the cores 7 are insulated from the pins 4 and the cores 7 are electrically connected to the housing 1.
  • the cores 7 serve, in addition to their effect as inductors, as electrodes of a capacitor, the other electrode of which is the pin 4 represents. This results in a certain resonant circuit effect, which further improves protection against high-frequency interference currents. Since amorphous or nanocrystalline tapes are cast directly from the melt into extremely thin-walled tapes, the cores wound from them can be dimensioned so small that they can also be attached to pins whose spacing is less than, for example, 4 mm from one another.
  • the effect of the damping device already results if only one pin is provided with such a core.
  • An improvement is achieved, however, if several or all of the pins of a plug are surrounded by such a ring core.
  • each pin is to be provided with a ring core, it is necessary to choose the outer diameter of the ring core to be smaller than the free space between two pins 4.
